I build intelligent systems — from RAG pipelines and knowledge graphs to conversational AI. Currently transitioning fully into AI Engineering, combining 6+ years of software craftsmanship with modern LLM architectures.
About me
I'm a software engineer based in Germany with a Master's in Applied Computer Science from the University of Duisburg-Essen. Over 6 years, I've built web applications, conversational AI bots, and recommendation systems — and I'm now focusing entirely on AI Engineering.
My hands-on experience with LLMs, RAG architectures, knowledge graphs (Neo4J), and AI platforms like Cognigy and Botpress gives me a practical edge: I know how to design, build, and ship AI systems end-to-end.
I'm curious, collaborative, and driven by the challenge of making AI useful for real people.
